Cycles per instruction : ウィキペディア英語版 | Cycles per instruction
In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: the average number of clock cycles per instruction for a program or program fragment. It is the multiplicative inverse of instructions per cycle. ==Definition==
Cycles Per Instruction is defined by the following:
Where IIC is the number of instructions for a given instruction type, CCI is the clock-cycles for a given instruction type, IC is the total instruction count. The summation sums over all instruction types for a given benchmarking process.
